| Abstract: | It is reported that by the addition of acetone to the sample solution,in the FAAS analysis the sensitivity of determination of iron is about 30% higher than that without the addition of acetone,while the sensitivities of Cd? Cu and Pb are not significantly effected. Based on this fact,the determination of Pb,Cd,Fe and Cu in zinc ingots of different grades can be carried out sequentially in a same sample solution,under the optimized working conditions. Results obtained by this method check well with those obtained by the standard methods. |
